CEL Common issues?
Hey, my girlfriend just noticed that her CEL was on today. I have a scanner at home but wont be able to get to her car for a couple of days. Anyway I was just wondering if there is a really common CEL related issue on these cars.
Also I was reading somewhere about checking the codes through the display? Is this possible? If so how is it done?
Thanks
(her car is a 2003 2.5 x-type)

SVTMFL, the code you have is "P1647 Linear O2 Sensor Control Chip (Bank 2)" That would lead me to believe you have either a bad O2 sensor (heater portion of the sensor has failed) or the wiring to the sensor is bad (wire is grounded to the body of the car). For reference, Bank 2 is the side of the engine nearest the radiator. If this doesn't fix the issue, then you have a bad ECU. But, based on what is most likely to fail, the O2 sensor is your most likely suspect.

ok, well finances are going to be kinda tight for the next couple months, will any long term damage (ie cats) be done by putting this off for a month or so? btw she only drives short distances like to work and school (only about 10 mi each way) so its not like we will be taking any long trips or anything.
Thanks
Thanks

The code is just telling you that the 02 sensor read out of spec. As already stated, could be bad wiring, could be a bad sensor but it could have just been brought on by bad gas, carbon build up lugging the engine uphill (subarus are famous for this). Did it go away with a reset? If so then I wouldn't be too concerned unless it comes back. With most of the emissions stuff I've always found that driving my wife's car usually helps to clear it out. She isn't the most spirited of driver. Usually shifting around 3k. A nice 6k drive for a bit seems to help clean out the system of build ups. At the very least it is a good excuse for doing it. Since she does a lot of short drives, that could be a contributing factor as the engine never heats up to burn off the water and other deposits which form in the exhaust.

Since it did come back on after the reset, yes I would be replacing it ASAP as an 02 sensor (or wiring issue to the 02 sensor is much cheaper than a Cat.

I figure that if it starts to run rich (or lean) that one of the other 02's would throw a rich/lean code. also it takes quite a long time of running rich/lean (moderately of course) to damage the cats permanently. either way it will probably be going to the shop in the next couple of weeks.

Thanks for all the replies, the car was going to go to the shop on friday...but unfortunately she (my girlfriend) was in an accident last night everyone is ok but it still kinda sucks. I'm pretty sure the only damage done to the jag was the hood/headlights/front bumper/radiator. Beyond that everything still looked good. Ill post pics when it gets fixed.
